"I don't have any regrets," Ashley told ET. "It made me who I was, but you get caught up in tabloids and stuff and it overtakes your work as an artist."

The 40 year old has lived through two failed marriages (he was married to Shannen Doherty for five months in 1993 and wed model Angie Everhart in 1996 before they split a year later), a heroin addiction and struggles with anorexia and bulimia. Today, Ashley is eight years sober and living a new life.

"I think the era of bad boys is gone. There needs to be more bad boys," he joked.

The actor and singer-songwriter gets candid about his past in E!'s Stewarts & Hamiltons, which premieres Sunday.

The series follows his blended family, as well as his own music career with his band Ashley & the Lonely Hearts. One of Ashley's biggest hits came in 2003 when he released the single "Wimmin'," which reached No. 27 on the U.K. Singles Chart.

"Music became this healing thing, and the music is through the whole show," Ashley said. "There is a lot of healing through music."
